To all TUhOHI/ it may cmtcmw:

Be it known that I, SAMUEL L. ALLEN, a citizen of the United States, and a residentof Moorestown, State of New Jersey, have invented certain new and useful Improvements in Agricultural Implements, of which the following is a full, clear, and exact'description,

' of crops and which has many uses and advantages both in its mode of operation and construction not heretofore existing in this class of agricultural implements.

Another object of my invention -is to provide a novel construction of tool carrying frame having mechanism for adjusting the width of thesaid frames during the operation of the machine, so as to bring the tools either closerto or farther away from the plants being worked in the event of the rows being uneven or varying in width.

Afurther object of my invention is to provide a lever mechanism for tilting the entire frame of the machine, which lever also serves to raise or lower the tongue, and in providing independent levers connecting with each of the tool-carrying frames for raisingand lowering the same. which act in conjunction with the first-mentioned lever and serve to regulate the depth of the cut of the tools in the soil.

Further objects, uses, and advantages will be apparent on reference to the following description when taken in connection with the accompanying drawings.

Referring to the accompanying drawings in which similar reference-numerals are used to indicate like parts, Figure 1 is a plan view of a machine constructed in accordance with my invention. Fig. 2 isa side elevation of the same. Fig. 3 is a front view, and Fig. 1 is a sectional elevation taken about on the line 1 4 of Fig. 1. Fig. 5 is a perspective view of a detail.

In carrying out my invention I provide a supporting frame comprising a transverselydisposed bar 1, whichcarries the clamps 2, in which are; mounted the vertical pivot-bars 3,

having their lower ends bent at substantially right angles to form axles 4 for the supporting-wheel 5. The clamps 2 are adjustable laterallyv on the frame-bar 1 for the purpose of adjusting the distances between the supporting-wheels of the machine.

Pivotall-y secured to each end of the framebar 1 is a U-shaped frame 6, preferably constructed of angle-iron or steel. This i ranie 6 is provided with two diagonally-disposed braces, as 7 which are riveted at dne end to the front portion of the arched frame 6 and at their other ends to a lug 8, carried by the box 9, which is secured on the lower'end of each of the pivot-bars3. The U-shaped frame 6 is further braced by means of the bars 10, which are secured at their front ends to the forward part of the said frame and at their rear ends to the frame-bar 1.

1n the forward part of the machine 1 pro vide a transversely-disposed frame-rod 11, havinga yoke-shaped central portion 12, which extends upwardly and rearwardly and is secured to the under side of the brace-bars 10 by means of suitable clips, as shown at 13 in Fig. 4 of the drawings. The sections 11 of the frame-rod extend transversely to the machine. as shown most clearly in Fig. 1 of the drawings, and reach some distance beyond each side of the arched frame 6. A bracerod 14 is connected to the outer ends of the rod 11 at their lower ends and at theirupper ends to the under side of the front portionpf the U-shaped frame 6. Another brace-rod, as 15, is secured at its lower end to the end of the rod 11 and runs rearwardly and upwardly and is secured at its upper end to the under portion of the side sections of the frame 6. These braces 1 1 and 15, together with the clips 13, serve tohold the frame-rod 11 12 securely in position on the main frame of the machine.

On each of the transversely-disposed sections 11 of the frame-rod I provide a sleeve 16, which is adapted to slide on said rods in the manner hereinafter described. This sleeve 16 carries a clamp 17 which projects from the rear of the rod 11 and supports and holdsa bar 18, which runs substantially parallel with the frame-rod 11, as shown in .Fig. 1 of the drawings. throughan eye 19, which is formed on the sleeve-l6. At the inner portions of the transversely-d isposed sectionll of the frame-rod This barlS has its inner end passing ZOO ' 3 of the drawings.

I provide the collars 20, which have a projecting web or flange 21 extending from their rear portions and to which is secured one end of the hinged tool-carrying frames. The other side of the tool-carrying frame is pivoted at its forward end to the outer end of the bar 18. The tool-carrying frames are preferably constructed in the form illustrated in Fig. 1 of the drawings and comprise two independent side bars, as 23 and 24, which are hinged together at their rear ends by means of the bolt 25, which passes through a casting 26,.secured to the side bar'23, and through.

an eye 27, formed in the end of the side bar 24. The side bars 23 and 24 of the tool-carrying frames are preferably constructed in the manner illustrated in Fig. 2 of the drawings. In this figure it will be noted that the forward section 80 of the side bars is elevated, so as to be in a plane above the rear section 81. The object of this construction is to permit the use of the high standard tooth, such as illustrated at 82 in Fig. 2. The end of the bar 24 extends a short distance in front of the eye 27 and is connected at this point by.

means of a rod 28, which is connected at its upper end to one of the levers for raising and lowering the tool-carrying frame,- which will be described hereinafter.

Extending from the inclined yoke portion 12 of the front frame-rod is an arm 29, which is'braced by means of the bar 30, which is connected to the outer end of the arm 29 at one end and to the frame-rod 12 'at its other end in themanner shown most clearly in'Fig. A bell-crank lever 31 is fulcrumed at 32 to the arm 29 and has its other end rigidly secured to a lever 33, which has pivoted to its lower end a link 34, which link is pivoted at its other end to a'lug 35, formed inthe sleeve 16. The upper end of the bar 33 is pivoted to bar 36, which is in turn piv oted at its upper end to an arm 37, secured to the operating-lever 38. This operating-lever 38 is pivoted to the segmental rack 39, which is supportedon the frame-bar 10, and is provided with the usual pawl mechanism, which is adapted to engage the teeth of the rack. From the above description it will be readily seen that upon operating the lever 38 the bellcranl; lever 31 is actuated, and through the medium of the connecting-link 34 the sleeve 16 and clamp 17, which carries the bar 18, are

- moved laterally on the frame-rod 11, and by reasonof the connection of the bar 18.with the outer sidebar 24 of the tool-carrying frame the said tool-carrying frame may beadjusted at its forward end so as to accommodate any unevenness or deviation in'the width of the rows of plants being cultivated. This adjustment can be effected during the operation of the machine by the operator,and when the outer side bars of the tool-frame are moved outwardly by the lever mechanism just described the hinged portion of the tool-carrycoated ing frame also moves in the same direction by only about one-half the distance of the front 'end of the side bar.

This keeps the tool-carrying frame symmetrical at all times. The width of the forward portion of the tool-carrying frame can be further adjusted-and regulated by releasing the clamp 17 and moving the bar 18 in or out, thus Widening or nar-' rowing the normal width of the said tool-car- I rying frame to accommodate rows of ditferent widths. The inner side bar 23 of the toolcarrying frames is capable of a lateral adjustment, as the web or flange 21, carried by the collar 20, is provided with a number of bolt-g holes in alinement in which the end of these side bars may be pivoted. The bar 18 is preferably provided on its upper face with a series of graduations, so that the said bar may be set according to the number of feet or inches between the rows.

Secured to the clamps 2,carried by the framebar 1, adjacent their outer ends are segmental racks 40, and pivoted to the segments are operating-levers 41, having the usual sprin pawls adapted to engage the teetu of the races for holding the levers in their adjusted positions. livotally secured to the levers 41, on each side thereof, are the twin bars 42, which are connected to bars 43, having their lower ends pivoted to the clips 44, which are secured to the projecting ends 45, provided on the ends of the tool-carrying frames. The'upper ends of the barsj43 pass between the twin bars 42 and are bolted thereto by means of. the bolts 46, which pass through the said twin bars and through longitudinal slots 47, provided in the bars 43.

A clip 48 is bolted to the ends of the twin 1 by each tool-carrying frame in the ground under tension and at the same time'allow the said frame to yield upwardly in the event of the'tools or teeth striking against stones or other obstructions. The depth of the cut into the soil may be readily adjusted by the operator by pushing the lever downwardly, where it may be' held in such adjusted position by the rack and-pawl mechanism provided. The tool-carrying, frames can also be lifted so as to bring the teeth entirelyclear of the ground by raising the lever41, as will be readily understood.

In the center of the machine between the two bars 10 I provide a segmental rack 51, which is secured in position by means of a foot-piece 52, adapted to rest and be bolted to the upper yoke portion of the frame-rod12 at one end and having its rear end provided-with an extension 53, 'which is bolted to the framebar 1. A lever 54 is fulcru'med to the segment 51, which is provided with the usual spring-pawl adapted to engage the teeth of the rack. Pivoted on each side of the lever 54 are the twin bars 55, which extend toward 'the front of the machine and are pivoted to a stirrup 56, which hasits free ends bolted to I vers, to regulate the depth of penetration of the tongue 57 by means of a pivot-bolt 58. This bolt 58 also passes through the angleirons 59, which are secured to the front part of the arched frame 6, as illustrated in Figs. 1 and 3 of the drawings. Pivoted between the two bars by the bolt are the bars 61 and 62, which extend forwardly and are inclined downwardly, where they are bolted at 63 to wardly, the entire supporting-frame of the machine is tilted, which action raises the front end of the tool-frames and also lowers ortilts the rear ends of the said frames. Consequently this lever 54 acts in conjunction with side lethe tools into the soil.

The wheel-pivots 3 have secured to their inner sides the foot-rests 65, by means 'of which the operator may turn the said pivots to steer the course of the machine. The two vertical pivots 3 are connected together by means of a bar 66, which extends transversely across the machine and is pivoted in its center by a pin 67, passing through an eyelet .fdrmed on the lower portion of the segment 51. At each end of the bar 66 is pivoted a rod 68, which is connected at its other end to the vertical wheel-pivot 3, so that when the operator pushes one of the foot-rests to turn the supporting-wheel at an angle the connection between the two pivot-bars will serve to turn the opposite wheelat a similar angle.

The seat-frame 7 0 comprises two parallel bars secured at their front ends to the yoke portion of the frame-rod12 and having their intermediate portions secured in any suitable manner to the frame-bar 1.

The draft mechanism of my machine may be described as follows: a doubletree 71, composed of two metal bars, the upper -one of which passes over the top of the tongue and the lower one passing under the bottom of shown in Fig. 2 of the drawings.

the tongue, the two said bars being pivotally connected to the tongue by means of the bolt 7 2 and having their ends bolted together, as The end bolts 73, provided in\ the doubletree, terminate in hooks or staples, as 74, to which is connected a vertically-swinging bar havportion of said frame.

ing a series of apertures provided in its lower end, to which may be connected the clevis 76, which carries a. swingletree 77. The end of the bar 75 is connected, by means of links or a chain, as 78, to an eye formed on the sleeves 16, carried by the frame-rods 11. By such a construction the draftof the machine is equalized in a very eflicient manner.

In the operation of my machine the toolcarrying frames are first adjusted at their forward ends to suit the width of the rows to be worked by loosening up the clamp 17 and adjusting the bar 18 laterally, which adjustment moves the outer side bar 24 of each tool-carrying frame laterally. The inner side bar 23 of each frame may be adjusted by removing the connecting-bolt provided in theend of said side bar and placing it in a different hole provided in the web or flange formed on the collar 20. After these adjustments have been made the operator can increase or diminish the width of the tool-carrying frame by operating the levers 38. These levers 38 are each independent of theother and are connected to the sleeve'16, carried by the transversely-disposed frame-rod 11, by means of the bell-crank mechanism heretofore described. The operation of either of these levers moves the outer side bars of the tool-carrying frame either in or out, so that any deviation in the width of a row may be accommodated and the teeth be made to work the same distance from the plant throughout the entire length of said rows.

By means of the independent levers 41, provided on each side of the machine and having connection with the tool carrying frames, each of these said tool-carrying frames can be adjusted relatively to the soil, so as to obtain the proper depth of penetration of the tools independently of each other, as before described. The levers 41 also serve as a lifting means for raising the tool-carrying frames and their tools out of contact with the soil during transportation from the field. The central lever 54 serves to raise or lower the tongue of the machine and also serves to tiltthe main supporting-frame and Wheel-pivots, which action necessarily raises the front portion of each tool-carrying frame and lowers the rear Therefore the said central lever may be said to act in conjunction with the side levers 41 for regulating the depth of penetration of the tools into the soil.

Itwill be noted that the peculiar combination and arrangement of the various parts of this machine adapt it to various kinds of work in the cultivation of crops and render it operative under all conditions of soil.

The machine isalso very simple in itsconstruction and inexpensive to manufacture, and

at thegame time the movements are all positive, arid the machine is extremely strong and durable.
